           Summary: iframe loads with wrong (old) url
           Product: WebKit
           Version: 525.x (Safari 3.2)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Frames
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: toomim at cs.washington.edu


I am building a facebook app that loads an iframe. I've noticed a few times,
though, that if I change the url for the iframe (the src attribute), safari
continues to load the iframe with the OLD src attribute when I reload the outer
page.

This is really strange. If I view source on the outer page, it shows the
correct (new) src attribute. But the iframe is loading the old one. If I
control-click on the iframe and tell it to open in a new window, it pulls up a
browser for the incorrect (old) src attribute url. Emptying the safari cache
does not make a difference.

My iframes usually just change in the get request parameters (the base url
filename is stable). Here's an example. Check out the discrepancy is the
fb_sig_session_key parameter!

-----------------------
iframe code that shows up in view source:

<iframe
src="http://together.cs.washington.edu/cgi/toomim/ourprivates/toomistage/upload_iframe.php?fb_sig_in_iframe=1&fb_sig_locale=en_US&fb_sig_in_new_facebook=1&fb_sig_time=1235281190.6003&fb_sig_added=1&fb_sig_profile_update_time=1235040526&fb_sig_expires=1235286000&fb_sig_user=10726833&fb_sig_session_key=2.2x_lqPx6gDanLxewlviX8Q__.3600.1235286000-10726833&fb_sig_ss=1ZznCtAXXcC31z3s4H4Y1Q__&fb_sig_api_key=602c044424a1b87d1b1c3759aed8c2ac&fb_sig_app_id=37504431558&fb_sig=87171174852074ae7be632d873cc56c4"
name="main_iframe" smartsize="false" resizable="true" frameborder="0"
scrolling="no" class="canvas_iframe_util"></iframe>

------------------------------------
iframe url that safari actually loads:

http://together.cs.washington.edu/cgi/toomim/ourprivates/toomistage/upload_iframe.php?fb_sig_in_iframe=1&fb_sig_locale=en_US&fb_sig_in_new_facebook=1&fb_sig_time=1235267726.0654&fb_sig_added=1&fb_sig_profile_update_time=1235040526&fb_sig_expires=1235271600&fb_sig_user=10726833&fb_sig_session_key=2.csZlTdDRokWIkZOWN7XLlQ__.3600.1235271600-10726833&fb_sig_ss=BKLMYeflNsDMy7cYQI8pZQ__&fb_sig_api_key=602c044424a1b87d1b1c3759aed8c2ac&fb_sig_app_id=37504431558&fb_sig=05c2017739101fd7597835c92618cd7e

This latter url is one that used to be correct! Somehow safari has saved it and
continues to stubbornly reuse it even though the page is telling it to use a
totally different url.
